All children accomplish ...

All children accomplish milestones in their own way, in their own time.

Quotes from the same author

Focus on quality and ease of movement, not on the age a milestone is accomplished.
 Magda Gerber
Allow the child to be authentic, to move, to feel the way they move, appreciating them for what they are.

Every baby moves with more ease and efficiency if allowed to do it at his own time and in his own way, without our trying to teach him. A child who has always been allowed to move freely develops not only an agile body but also good judgment about what he can and cannot do.
 Magda Gerber
What parents teach is themselves, as models of what is human - by their moods, their reactions, their facial expressions and actions. These are the real things parents need to be aware of, and of how they affect their children. Allow them to know you, and it might become easier for them to learn about themselves.
